shaft being-formed with a-longitudinal bore 59, communicating at itslower terminus with thechambered body of said head 58 and at'its u perextremity with a suitableexible mem er orLtube 60, which leads to acont-rol valve, not shown, for admitting aA fluid medium or super and/orsubatmoshere to the head or chuck or gripping memer dpreferably in amanner shown and describe in my Acopending ap lication-just specified,theshaft 57 prerably being where it extends through the bracket 56, athreaded nipple 62 being inserted the said bracket and communicatingwith said recess,

-so that the desired uid medium ma be ad.-

mitted to the ware'grip-head or c uck 58 through the bore of the shaftduring rotative or reciprocatory movement of the latter. A friction gearor disk 63 is resiliently mounted on the upperextremity of the shaft p57, and to rovide for such resilient mounting, I vre er to form atransverse bore in the sha 4for insertion of a pin 64, the hub 65 ofthesaid gear being slotted, as at 66, and the pin 64 extendingthrough thisslot, a spring 6 tion gear-63 and a bearing collar 68, removably andadjustably secured'on the shaft 57 as on Vthe bracket 56. The friction.gear 63 is 4adapted to coact with a similar gear 70, ad-

justably secured" on a shaft 71 asv by a screw screw 69, said collarhaving bearing being interposed between the fricv Z'Oextending throughthe hub of said gear,

(see Fig.- 3), The shaft 71 may be Adriven continuously through themedium of suitdrive shaft 74 and adjustably .mounted asv by screws 7 2@and 73a extending through the able bevel or mitre gears 72 and 73,respechubs of said gears. The ware pick-upand transfer and manipulatingassembly 'com- `grises other instrumentalitles which will be ereinafterdescribed. Shaft 74 is adjustabl mounted as by collars 7 4grt and screws74h.

El@ y ne `preferred.method of imparting vertical movement te the frame'44 and lateral movement to the bars 4,7 and 51, to thereby impart thedesired movements to the ware pick-upl and transfer and manipulatingassembly above s eciied, is to mount a canr shaft 7 5 in suite lebearings on the main sta'- l tionary frame 5, said shaft having securedthereon cams76, 77 and 78, adjustably secured as b screws 76, 'WB-and78a extending throught e hubs ci? said cams, the cam. 76

being adapted te impart vertical movement to the frame 44, the cam 77contacting with the bracket 54 to impart lateral movement to the -bars47andl, and the cam 78 impartin 112e vertical movement to the ware turn- 1ing an Vfinishing tools lwhen such movement v I is desired and foundnecessar and whichwill y I, ,v-e'cam'isv adapted to" contact with aroller 79,011 a leverv 3o mine 80," adjustably pivoted at one extremitythrough the medium o f the sliding block-ad- 'ustment heretoforespecied, as at 81, to a racket 82, which is secured to the platform 5 orbrace structure 43 as at 83, and said lever at its opposite extremit ishingedly or pivotally connected to the rame 44 through the medium of aterminal bracketl 84, threaded on one extremity of a turn-buckle 85, theopposite extremity of the latter being threaded through a lug or ear 86,which may be formed integral with the frame 44, the turn-buckle 85providing for adjustment, while in o eration and without disconnectingthe driving connection, of the reciprocation of the frame 44. The camshaft 75 is here shown as being driven through the medium of suitablebevel or mitre gears 87 and 88, res ectively secured on the shafts 7 5and 74 anda justably mountzo ed as by inserting screws 87 a and'88athrough the hubs of said shafts.

By referring to my copending application Serial No. 203,186,heretoforespecifed, the

gears into contact with said operation of the ware pick-up and transfermeans will be readily understood as well as the means for selectivelyspotting the grip head and ware and causing the latter to move' in a(predetermined path between predeterpoints and the various advantageousadjustments incident thereto.

The cams 76, 77 'and 78may have an de-l siredsurface contour inaccordance wit the movements to be imparted to the parts primarilyactuated thereby. In the structure illustrated by Figs. 1, 2 and 3, thecam 76, (see Fig. la), for imparting vertical movement to thewarepick-up, transfer and manipulating assembly, may be formed withdepressions 7 6b andI 76, the cam 77 with a raised part 77b and a high"part 7 7., and the cam 784 with a raised part 7 8b and a high part 7 8.

lThe ware turning and finlsqhing instrumentalities which em ody thefeatures of the present invention are illustrated herein in a number ofdiiferent forms but the general principle of the invention is the same,and it will be understood that obvious variations and adaptations may bemade without departin from the scope of the inventionvas claimev vReferring to Fig. 1, the numeral 89 desi nates a supporting member orbar'or shagt, vertically disposed in the present instance and slidablevertically in brackets 90, suitably secured to the main stationary frame5 as at 91. A' lever 92.is adjustably pivoted at one extremity, as at93, to the stationary bracket 82 through vthe lmedium of the slidingblock. adjustment heretofore specified, a caml roller 94 being rot'atablmounted on said lever and contacting with1 cam78, and at its oppositeextremity thislever is pivotally and adjustably connected to the upperend of the shaft-89 as by turn-buckle 95. Brackets 96 between thebrackets y96 an illustrated in and 97 are mounted on the shaft 89 andadapted to have turning movement on said shaft.

in a horizontal plane, the brackets 96 bein supported by bearing collars98,l secured an adjustable on shaft 89 as b screws 98", and

89 I prefer to mount supplemental abutment brackets 99, adjustablysecured as by screws 99, adjusting screws 100 being threaded throughthese brackets and abuttmg against said brackets 99, see Fig. 3, for a'purpose to be explained, the brackets 96 and 97 being connected andmaintained under lateral tension as by a spring 101, adjustably securedto each of saidbrackets.

Thebrackets 96 and 97 serve to support tool-su portingkmembers or bars102 and 103 particu arly shown in Fig. 4, a cutting tool 97 on saidshaft 104 and finishing and vburnishing tool 1054 being secured on thelower portions of these bars, each tool beingpreferabl independentlydriven b a motor 106 in t e structure ig. 1, the motor and tool vas aunit being universally adjustable as shown in Fig.l 4a, a clamp 107being mounted on each shaft 102 and 103 andad'ustably secured as byscrew 108, said clam eing bored for insertion therethrough of a urtherscrew 109, threaded at one extremity into a block 110, adapted tosupport the motorl and tool assembly, the motor sleeve 110a extendingthrough said block and adjustably secured as by screw 110". Through themedium of screw 108, the tool assembly may be adjusted vertically onshafts 102 and 103; by screw 109, the angle thereof may be varied oradjusted,

and -by screw 1101, the assembly may be adjusted horizontally, eachadjustment being independent of the other. Each .tool is removable andre laceable on the armature or motor shaft as y screws 111. At asuitable distance above the tools 104 and 105 on bars or rods 102 and103, pattern-cam contour-following and guiding tools Aor stylus vmembers112 are removably and adjustably secured in brackets 113 as by screws113,

these tools 112 being adapted to follow any desired contour orpatternwhich may be formed on a pattern cam 114, removably andadjustably and, if desired, rotatably mounted on the shaft 57 carryin'the grip head or chuck 58 through the me ium of u er and lower 'collars115 and 116, vadjustae as by screws 115a and 116, the u per 'collarbeing fast to the pattern cam and) the lower collar being a bearingcollar forsaid cam in the event it is desired to rotate lsame on shaft57.

It may sometimes be desired to rotate the pattern cam 114 independentlyof or at a different rate of speed relatively tov the-warebeing operatedupon, to increase orreduce the size ornumber of gures producedl on theware relativel to the pattern cam, in.

avancee being suitably secured to' and rotatable with the pattern cam114, see Fig. 4, the gear 118. being removably and adjustabl secured toVas by screw 119%' said idler gears 119 and l 120- preferably being Vcastintegral and hav.- ing earing Aon stub shaft 121. Varying speeds ofrotation ofthe pattern cam 114 may be obtained by substitutinroper sizedgears, as will be understood. Y hen it is desired to Yrotate saidpattern cani n114-, screw' 115a may be retracted from contact withshaft' 57, as will be understood.

A bottom turnin and finishing tool 122`is removably and a Justablysecured on the lower end of shaft 89 'said tool having a contour f thesize and s ape of the bottom of the ware and formed with anarm 123terminating in a hub 1211, adapted to lit over the shaft 89 and Thescrews 100 serve to positively limit the movement of the tools 104, 105and 112 in a direction towards each other, to facilitate movement of thepattern cam and ware therebetween, and also by this means the depth ofcut maxlbe limited regardless of the patterncam 1 adjustably secured asby screw ient. These screws'may be adjusted relatively to the sizeof theware being operated upon, When turning and finishing ware having 1irregularities thereon such as flutes, ribs',etc.,

collar 68 ma and oval shaped ware, it may be necessary to definitely sot the angular position of the head 58 an pattern cam 114 relatively tothe ware in or on the molds, in which event the a latch 68 beingpivotally mounted on brack. viat-56 as at 68 and under s ring pressureas by spring 68@ and norma y pressed into v notch 68B. A hook 68 isadjustably threaded on'a stud bolt 68i and maintained in adjustedposition as by'set nuts 68g, said bolt- 68 'inf turn being adjustablythreaded in frame 44,9; lhook-engaging pin 68n being suitably secured inthe upper extremity ot the latch 68.' en the bar 47 carrying the warepick-up and manipulating and transfer assembly and pattern cam 114 isshifted to the left as viewed in Fig. 1, hook 68e may be` adjusted onstud bolt 68Z so as to contact with Apress latch 68 back intoregistration with notch 68a and thus prevent `further rotation orangular movement of shaft 57 and head t, while the o posite directionot-- movement of said tools 'is maintained resil.

By obvious modifications instructure, not shown, additional cutting and inishin andcontourfollowing tools may be adde and by using a multiple of cuttingand burnishing tools, the operation maybe expedited. Itl may also bedesirable to employ one or more tools as roughing tools and others asfinishing tools, to cut in sharp or intricate designs. a In Fig. 2 waremay be turned while rotat-v ing in one direction and burnished byimparting a reverse rotation thereto, the same tool being used to'perform both operations. In this instance the friction drive disk 70 isformed with a sleeve see Fig. 3, formed at one extremity with an annulargroove 7 0, the said sleeve being in lon `tudinal.spline slidingengagement with t e shaft 71. vA

The turning and fini hing and burnishing tool 104, see Fi .3, is guidedby a roller 130,

at -131 to the main stationary frame 5, a sprin 130, secured at opA siteends to lever 92 an shaft 89 respective y,serving to maintain the roller130 against the attern 114". The tool 104l may be shaped su stantiallyas shown in Fig. 2*, in whichinstance the ware to secure the bestresults, should be rotated counterclockwiseto turn the same andclockwise to burnish'. l An edge finishing tool 132 is adjustablysecured .to the shaft or bar 89 as at 133, so that ugh the hub of saidwhich is rotatab y moun ed on a sleeve on the .motor shaftor in any oter suitable manner, said roller following the contour of a pattern orprofile member 114, adj ustably secured as it will contact with andfinish the edgeof-th'e ware approximately at the -time the tool 104* hasoperated on the lower outer surface-por- In operation, the ware may beturned while the tool 1 04 is being lowered or raised, de-l sending-uponadjusted osition'of cam 78,

In Fig. -10 a bottom cutting tool 159 is provided in addition to theburnishin tool 122.

By adopting the construction il ustrated in Figs. 8, 9, 10 and 11 theware may be turned 4o and finished while moving in one direction duringthe o eration of transferring the ware from the mo ds to the forms onthe conveyor D. By slightly modifying cams 76 and 77 relatively to'similar cams shown in Figs. 1,

Figs. 17 and 18 illustrate a modified form l of turnin and finishing andburnishing assembly. ing tools 104 and burnishing tools 105 may beadjustably mounted in supporting brackets 168-and 169, as by slots 176and 171 and securing bolts 172 to provide for both vertical and lateraladjustment, the bottom cutting and burnishing tools 122l and 159beingmounted in a similar manner in bracket n this instance the cutting orturnizo 173. Bracket 169 maybe rotatably mount- .ed on a spindle 138andthe assembly rotatedl if desired by suitable driving means or amotor, or the. ware onl `may be rotated, or both ware and' assem lyrotated in opposite directions.

Insome instances it may be desired to finish. the interior of the ware,and in Figs. 19,

l finish the bottom of the ware prior or subse-V l from the mold toturnV and finish the interior Y 2O and 2l I have shown an assembly whichmay be adopted with this end in view. This interior finishing assemblymay be disposed to operate prior or subsequent'to the ware iinishingstructures hereinbefore described, the interior nishing operationpreferably ensuing while the ware is in or on the molds, and to maintainthe ware in stable position v while being operated upon, I prefer toadopt the type of mold and chuck and appurtenant parts Vas disclosed bymy cope.

Thus when an article of ware isdisposed on the mold lai-'lyillustrated by Fig. 20 being an example of a cutter adapted for deepware, and that Y illustrated in Fig. 21 an example of a 4form of cutteradapted for shallow ware such as vplates where it may be desired to turnand quentto being operated upon by the strucltures shown by Fig. 12.

The shaft 57 in the form shown by Figs.

19 and 20 may be constructed and mounted in a manner substantially asshown in Fig. 16,'

the bore '59 in this instance communicating at its lower end with a bore59 formed in the tool 104. However, instead of applying subatmosphere asa gripping medium to remove or transfer theware, this construction maybe adopted lfor removing cuttings and particles resulting trom theoperation of the tool 104-, it not being necessary to remove the warethereof. If it should be vdesired to remove the cuttings and particlesin the form shown by Fig. 21, the guardor housing construction Yillustrated inFig. 5 may be adopted.' `The 1 tools '104 'are removablyand. adjustablyl threaded on theshat 57 and maintainedin adjustedposition as by set nut 174. 1

As it is preferred vto simply impart vertical movement to the turningand finishing assembly in the form shown by-Figs. 1 9, 20 and 21, it maybe desired to maintain the bar 47 against lateral sliding movement, inwhich event a set screw 178 maybe provided in frame 44 and adjustable tobear-against .said bar.
